Description

HBASE-27769 used the new Hadoop API (available since Hadoop 3.3.6/3.4.0) to access recoverLease() and setSafeMode() APIs, and committed the change in a feature branch.

However, until we move beyond Hadoop 3.3.6, we can not use them directly.

I'd like to propose to use reflection to access these APIs in the interim so HBase can use Ozone sooner.
